My concern is the yellowing not the silver which is normal. There's no pests on/under the leaves(that I can see). There are two plants in this box and the other one is not affected(yet). The only thing that's ever happened to my zukes is PM which comes later in the season. We have had way more rain and storms this season than usual and quite a few of my pepper plants have had the nutes washed out of them and were turning yellow. I've hit all the plants including the zukes with epsom salt and a weak MG solution and things are starting to green up, but this seems different. Any suggestions/advice is appreciated.
